This application is a division of applicants C? pending application Serial No. 437,232, filed April 1, 1942, which has resulted in Patent 2,373,492 granted April 10, 1945, and which in turn is a division of applicants application Serial No. 374,214, filed ,January 13, 1941, which has resulted in Patent No. 2,302,880,*granted November An object of the present invention is-to provide supporting means for the manifold of a stove, which supporting means are composed of sheet metal and are light in weight. q

A further object is to provide supporting means for the manifold of a stove, which supporting means has few and simple parts and is well adapted for commercial production.

Further objects will appear, as the description proceeds.

Referring to the drawingsa v Figure 1 is a plan view of the stove in open operating condition;

Figure 2 is a section taken on line 22 of Figure 1; and

Figure 3 is a' fragmentary section on an enlarged scale, taken on line 33 of Figure 1.

The stove is housed in a two-part housing member or box which comprises the base or bottom member II and the upper or cover member [2, said members being hinged together.

The housing members II and I2 are preferably formed of metal stampings and have the outwardly embossed sections I8 and 19 formed thereon, these serving not only to add to the appearance of the housing, but also to stifien the housing members and to render them more rigid. It

will be understood that the bail bracket clip, latch and hinges may be spot-welded or otherwise secured to the housing members.

The stove enclosed in the housing is shown in operating position in Figures 1 and 2. The housing member I l is swung down to rest on the portions 19 and also upon the bail 0r handle I which is turned downwardly as clearly shown in Figure 2. The member I2 is swung upwardly at an angle of approximately 90. The manifold 20 is L-shaped in generalform, comprising a bottom member 21 which is arcuate in cross-section, with outturned flanges '22 as shown in Figure 3. The manifold has the upper member 23, the greater part of whose surface area is flat, this member having inturned edges 24 crimped around in substantially gas-tight contact with the outturned flanges 22 of'the lower member.v

1 The manifold is supported from the inner face of member II by means of the bracket 25." This bracket 25 is provided with spaced upturned ends 26 and 21, which are each formed with anarcu- :3; ate recess28 toreceive the manifold. The upf turnedends 26 and 21 are provided with cars 29 and 30, which engage the upper face of the manifold to hold it firmly in place. It will be apparent that since the bracket 25 is formed of lo sheet metal, the ears 29 and 30 may be readily bent to permit insertion of the manifold, and when returned to position after insertion of the manifold will rigidly hold the parts in assembled relation. 7' 7 id The upper plate 2301f the manifold is provided Withan opening 3| having adownturned edge, as shown in Figure 2, and a main (burner 32 is spot-Welded to the manifold concentric with the opening 3|. A second burner 33 is shown in 20 Figure 1'.-

The rearof the manifold assembly i supported by, the clip 52, which is spot-welded to the inner face of the bottom of housing member H.- The air intake shield 53 is fitted on the mani- 25 fold between the Venturi member 41 and the burner 32, and is provided with an opening receiving the small end of the Venturi member 41. An air intake opening 54 is located below the venturi, and an inturned flange 55 forms an opening 30 to receive the end 56 of the gas generator tube 51. The member 53 therefore serves as a'combination generator support, air intake shield and Venturi support. This member is held in place on the manifold by inturned ears, one of which is indicated at 58.

The gasoline tank 59 is provided with the usual filler plug 60 and supports the valve body 6|, which in turn supports the generator tube 51. This valve body 6 I is shown as provided with the usual main control valve 62 and the starter valve tank 59 has welded thereto the supporting brack- I et 64. This bracket 64 has an upper inwardly extending portion'65 with aninturned end adapted to hook over the edge of housing member II, as shown in Figure 2. In addition, the bracket is provided with a lower inwardly extending flange '66, which is notched to engage the end portions These notches, fitting over the bail, serve to firmly hold the bail in place as a support for the stove and also to maintain the tank and generator tube assembly in proper assembled relation and alignment with the venturi and burner assembly. It will be noted that the size of the bail is such that when it is in the position of Figure 2 the burners are brought to a horizontal position with the portion of the housin member H adjacent the bail held up above the adjacent support.

The grate 61 is pivotally supported from the housing member l i by means of hinges 68, shown in Figure 1. Thi grate as shown in Figure 2 has a arcuate portion and downturned portion adjacent to the bottom of the housing, with a fiat portion extending over the burners when the stove is in operating position, as shown in Figure 2. The front edge of the grate 6'! is' supported by the sheet metal member 69, which is hingedly connected to the front edge of the grate and which has its lower edge resting on the line of junction between the bracket 64 and the tank 59. This member 69 has a notched out portion 69a to permit passage of the generator tube 51, as shown in Figure 1. This member 69 serves as a support for the front edge of the grate, but also serves as a heat baffie and a burnershield to shield the burners from Wind blowing in from the front of the stove.

The housing member l2 is held in upright position, as shown in Figure 2, by means of the windshield Wings H, 'H. These wings are supported from the member l2 by pivots 72- formed integrally with the wings and fitting in perforated support lugs 73 struck inwardly from the wall of the housing member l2. The wings are also provided with integral struck up stop members 74. These members 74 are adapted to engage the adjacent end walls of the member IE to put the wings under tension when they are in operating position. They are placed in operating position by being swung outwardly, as hown in Figure 1, and notch portions 75 are then hooked over the upper edge of the bottom member I I. Since the wings are formed of resilient sheet metal, the stops 14 act to resiliently hold the notches 15 in engagement and maintain the parts in assembled relation.

It will be noted that the stove as shown includes only a single casting, that being the Venturi member 41. All of the remaining parts are formed of sheet metal stampings which may be held in assembled relationship by spot-welding. The design reduces the number of parts necessary to a minimum, and these parts may be inexpensively and rapidly produced by commercial processes, The manifold is formed of two stampings, having an upper flat sheet metal memberto which the burners may readily be welded to secure an effectively gas-tight connection. This welded manifold may be cheaply constructed and substantially reduces the weight of the stove over that which would be required by a cast iron manifold. The burner assembly is rigidly supported in the housing by the bracket 25 and the rear bracket 52. It may, however, be readily removed by bending the retaining lugs on bracket 25. Its original assembly is effected quickly and easily by means-of theselugs- The inwardly extruded valve guide at the-second burner effectively traps in the manifold any gas condensed at this point. The upper flat manifold member has upwardly embossed portions over which the openings in the burner bottom plates 34 fit to make efiectivethe gas-tightjomt with these bot-tom plates when these are welded on the uppermanifold-member.

While we have shown a preferred embodiment of our invention, this is to be understood to be illustrative only, and we contemplate such changes and modifications as come within the spirit and scope of the appended claim.

What is claimed is:

In a stove, in combination, a sheet metal support having upwardly extending arms, said arms having manifold seats formed therein with bendable portions cverhanging the seats, said bendable portions being adapted to hold a manifold in place on said support.
